BELTING.

SPECIFICATION forming part of Letters Patent No. 619,908, dated February21, 1899.

Application filed April 27, 1898. Serial No. 678,949. (No model.)

To @ZZ whom, t may concern:

Be it known that I, HEINRICH THEoDoR REUTER, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inMachine- Belting; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machine-belting; and the objectis to provide a compound belt or built-up belt of this character wherebythe lap side will have a practically plane face in contradistinction tothat class of compound belts in which the lap forlns a longitudinalridge and is therefore unsuitable for contact with the pulleys.

To this end my invention consists in the peculiar construct-ion andarrangement of the filling, in combination with the inclosing sheath orenvelop, whereby the latter will encompass the filling, so as to form apractically plane lapjoint,whereby either side of the belt may beapplied to the pulley with the same cohesive result.

The invention further consists in the construction, combination, andarrangement of the several elements of the device, as will behereinafter more fully described, and partieularly pointed out in theclaim.

The accompanying drawings show my invention in the best form now knownto me 5 but many changes in the details might be made within the skillof a good mechanic without departing from the spirit of my invcntion asset forth in the claim at the end of this specification.

The same reference characters indicate the same parts of the device inthe several views.

Figure l is a perspective View of a section of a belt embodying myinvention. Fig. 2 is an enlarged transverse section of the parts inposition for making the lap-joint.

Fig. 3

is an enlarged transverse section of the complete belt.

l, 2, and 3 denote the longitudinal parallel strips of fabric whichcomprise the body of. the lling. These strips are practically of thesame dimensions, and their contiguous surfaces are cemented or otherwisejoined together, so as to form a flexible homogeneous iilling. 4 and 5represent narrower parallel strips similarly iiXed to the outer face ofthe filling-strip 3, so as to leave a longitudinal central channel 6between the inner parallel edges of the strips 4 and 5.

7 denotes the encompassing envelop, the free end 8 of which is trimmedolf to snugly fit the channel 6 between the strips 4 and 5. The oppositeflap 9 has' its free edge 10 skived oif to make apractically plane jointwith the shoulder or offset l2, caused by pressing the flap end 8 belowthe surface of the strip 4, so that the entire face of the belt Willpresent a practically plane surface when this side is applied to thepulley, thereby insuring the same cohesion as the opposite plane side ofthe belt would if it were applied to the pulley, thus enabling the beltto be reversed, so that when one side is worn the belt may be turnedwith its remaining face in contact with the pulley.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s-

A machine-belt comprising a filling, and the parallel strips 4 and 5fixed to said iilling, so as to form a channel between their inneredges, in combination with an encompassing envelop having its freelapped edges xed within said channel, substantially as shown anddescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

HEINRICH THEODOR REUTER.
